Abstract

Provided is a moving picture decoding method and apparatus. The decoding method includes storing coding information on a certain block and neighboring blocks, deriving a filtering coefficient to filter a boundary between blocks and predicting a motion vector of a certain block, based on the stored information, and filtering the boundary between the certain block and the neighboring blocks based on the derived filtering coefficient. Accordingly, the number of the memories and the amount of routing resources needed are reduced.
